Title: Multichannel analyser for spectrometer - has reference and measuring pulses fed simultaneously to compensate distortion of amplitude spectra
Inventor: KAMBUROV HRISTO KIRILOV
IPC: G01T1/40
Filed: 1975-12-19
Abstract: In a neutron-activation spectrometric operation a particle emission from a sample is detected and is converted in a multichannel analyser into a digital signal which identifies the particular channel corresponding to the pulse amplitude. A train of reference pulses of stable frequency is generated, having amplitudes falling within one group of the channels. The reference and measuring pulses are fed concurrently to the analyser. When a reference pulse coincides with a measuring pulse the system identifies a channel corresponding to the combined amplitude of the two pulses. This channel is within a second group of channels. The ratio of the reference pulse rate to the measuring pulse rate can be determined for a standard and test samples. This compensates for the distortion of the amplitude spectrum of a multi-channel analyser.

Title: Woodworking machine for boards on conveyor - has tools moving alongside work, with independent return
IPC: B23Q7/00
Filed: 1976-04-15
Abstract: A woodworking machine for boards (9) on a conveyor has two cutters (4, 5) under the board, which travel sideways (arrows A, B) and which are also raised and lowered (arrow E) to make the cut. They are then retracted until clear of the board, and back along the conveyor to the start. The paths of the two tools do not overlap, so that the front one (2, 4) which finishes its cut first, can start to move back while the rear one (3, 5) is still moving forward. As shown, the front one having completed its cut, is about to move to the right, while the other still cutting, is still moving left. Thus the front tool is back in time to deal with the following board, even though the spacing (a) between the boards has been reduced and the conveyor is, in consequence, more densely packed, and the rear tool likewise.
